I was looking for a log grapple for my Bobcat 743 skid steer and needed something not too heavy as my lifting capacity is limited. This unit fit the bill perfectly. It's reasonably priced and works very well. I've used it for clearing brush, stock-piling firewood trees, and loading saw logs on my log deck.
After a short learning curve I was able to sneak under logs laying together on the ground or pick one out of the pile with ease. It does everything I would expect.
There are two suggestions I would make as far as design:
1) Implement some sort of retaining device to route the hoses through that keeps them from getting pinched in the ram as it closes or hooked by a stray branch and dragged off to the side (I'm using bungee cords but they don't stand up for long).
2) Weld a ½" piece of pipe as a shield around the grease fittings to protect them from being broken off by impact with stray branches or debris (I broke one off in the first hour of use).
All in all, a great value. My only regret is that I didn't buy it years ago.
